Embodiment 1
[0020] A water supply pipe with self-cleaning and antibacterial function, including an inner layer and an outer layer, by weight,
[0021] The inner layer raw materials are: 65 parts of HDPE, 10 parts of lignocellulose, 10 parts of calcium carbonate, 2 parts of chlorinated polyethylene, 1 part of silane coupling agent, 2 parts of lubricant, 1 part of nano silver, 4 parts of zeolite powder and 0.02 parts of isothiazolinones.
[0022] The raw materials of the outer layer are: 65 parts of HDPE, 10 parts of lignocellulose, 10 parts of calcium carbonate, 2 parts of chlorinated polyethylene, 1 part of silane coupling agent, and 2 parts of lubricant.
[0023] Weigh the outer layer material and the inner layer material of the water supply pipe according to the proportion, mix them evenly, and then knead them separately. 190°C, and finally cooled to obtain a water supply pipe with self-cleaning and antibacterial functions.
Embodiment 2
[0025] A water supply pipe with self-cleaning and antibacterial function, including an inner layer and an outer layer, by weight,
[0026] The inner layer raw materials are: 70 parts of HDPE, 10 parts of lignocellulose, 10 parts of calcium carbonate, 2 parts of chlorinated polyethylene, 2 parts of silane coupling agent, 1 part of stearic acid lubricant, 2 parts of nano silver, zeolite powder 3 parts and 0.02 parts of isothiazolinone.
[0027] The raw materials of the outer layer are: 70 parts of HDPE, 10 parts of lignocellulose, 10 parts of calcium carbonate, 2 parts of chlorinated polyethylene, 2 parts of silane coupling agent and 1 part of stearic acid lubricant.
[0028] When preparing, weigh the outer layer material and the inner layer material of the water supply pipe according to the proportion, mix them evenly, and then knead them separately. 180-190°C, and finally cooled to obtain a water supply pipe with self-cleaning and antibacterial functions.
Embodiment 3
[0029] Embodiment 3: In addition to adding 2 parts of attapulgite to the inner layer material; the rest are the same as in Embodiment 2.

Abstract
The invention discloses a water supply pipe with self-cleaning and anti-bacterial functions and a preparation method thereof. The water supply pipe comprises an internal layer and an external layer; and 1-3wt% of nano silver, 2-5wt% of zeolite powder and 0.02-0.1wt% of isothiazolinone are added in the raw material of the internal layer. By adding the nano silver into the material of the internal layer of the water supply pipe, the nano silver has very good inhibition and killing effects on bacteria with negative charges because nano silver carries positive charges, and no drug resistance can be generated; the zeolite powder has the filling and enhancing effects as well as adsorption effect by adding the zeolite powder into the material of the internal layer, not only is water quality purified, but also slow releasing of nano silver can be promoted; and the isothiazolinone is easier to mix with a plastic material compared with the nano silver by adding the isothiazolinone into the internal layer, the problem of difficult to disperse is solved, the isothiazolinone has a good high temperature resistant property, and can jointly play the anti-bacterial effect with the nano silver, synergic sterilization can be conducted through an inorganic anti-bacterial agent and an organic anti-bacterial agent, the effect is better, and a long-acting anti-bacterial effect can be achieved.
Description
technical field [0001] The invention belongs to the field of water supply pipes, in particular to a water supply pipe with self-cleaning and antibacterial functions and a preparation method thereof. Background technique [0002] In modern urban water supply systems, high-density polyethylene (HDPE) water supply pipes are widely used because of their advantages of high strength, corrosion resistance, non-toxicity, and convenient installation. However, after HDPE water supply pipes are used for a period of time, a layer of viscous dirt will usually adhere to the inner wall of the pipe, which contains a large number of bacteria such as Escherichia coli and Staphylococcus aureus, which will directly endanger human health and provide a breeding ground for their reproduction. Contents of the invention [0003] The purpose of the present invention is to provide a water supply pipe with self-cleaning and antibacterial function and its preparation method, which can solve the defect...
